PETROLEUM-HEATER.

SPECIFICATION forming part of Letters Patent No. 560,014, dated May 12, 1896. Application filed OCtO JI 26, 1895. Serial No. 567,045. (No model.)

To aZZ whom it may concern:

Be it known that I, ERNST IVOLF, a subject of the King of Saxony, residing at Zwickau, Saxony, Germany, have made a new and useful Improvement in Petroleum-Heaters, of which the following is a clear and exact specifloat-ion.

My invention is an improved heater; and it consists, first, in the construction and arrangement of the heater proper, which is in the form of a lamp, and, secondly, in the construction and arrangement of the inclosin g shell or mantle.

In the accompanying drawings, Figure 1 represents a sectional view of the complete heater, Fig. 2 being a cross-section of the same on the line a h of Fig. 1. Fig. 3 is a detail view of the air-distributer.

In the drawings the base of the inclosing shell or mantle is shown at a and is preferably made of sheet or cast metal, provided with a series of air-inlet openings 7). Extendin g up from the base a is a sheet-metal body a, made of corrugated metal, as shown clearly in 2. Surmounting this body portion 0 is a sheet or cast metal top (Z, similar to the base 0, except that it is inverted. A deflector e, which is in the shape of a disk having corrugations radiating from the center thereof, is suitably supported at the top of the body with a space around its edge for the escape of the heat and with a central opening f. Direetly above this deflector is a water-tank g for providing the necessary moisture.

The heat-producer which I use is shown in the sectional view just within the base a, and it comprises a reservoir h of ordinary construction provided with a filling-orifice i and a central air-tube 717, which extends through the center of the lamp and is open at the bottom. A wick-carrier is shown at k in the form of a tube inclosing the wick and to which the wick may be secured, and this tube is fitted within a tube Z of larger diameter, this latter tube extending centrally from the burner proper, which is secured centrally of the lamp by its screw-threaded lower end. This burner carries a raising spindle and gear on, and the gear meshes with a rack secured to the tube 70, the end of the rack passing up through the burner in contact with the gear. The burner is provided with an outwardly-flaring skirt, which has a series of openings for the inlet of the air. A metal cap 12 fits the skirt of the burner and is removably secured thereto, and this cap is provided with a central tube n, surrounding the outer wick-tube, and is also provided with a support for the chimney.

Within the center draft-tube I locate an airdistributer, which is in the form of a tube 0, open at top and bottom and provided with a perforated disk 0, arranged centrally thereof, and to provide support for this tube I construct it with three radiating arms connected by a flange, as shown at p. The flange is circular and accurately fits the interior of the air-tube. The air-distributer tube is provided with a deflector at its upper end, as shown at q, and this turns the flame outwardly, flaring it. An air-passage is formed between the outer wall of the wick-tube and the tube at, and the air passing up through the same to feed the flame enters into this space through the series of openings '2' in the lower skirt of the burner.

The air for the combustion passes up the central tube around the outer side of the tube 0 and is deflected outwardly to the flame by the flange 1). The air passing through the tube 0 meets the mingled gases above the burner and aids in their perfect combustion.

What I claim is In a lamp, the tube land an outer shell having an air-passage between, the air-tube k, the interior tube 0 having the deflector at its open upper end and the perforated disk within, and means for supporting the inner air-tube 0 within the tube is consisting of the radial arms and the flange p fitting within the tube Ya.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
